Arris S33 modem w/ Xfinity 1.2Gbps service

Just started using an Arris S33 modem for my Xfinity 1.2Gbps link.  After reboot I get ~900Mbps downstream and ~6Mbps upstream.  Hours later I am getting ~25Mbps downstream ~4Mbps upstream.  I have checked the S33 cable signal levels and they look to be within expectations.  Is there anything else I need to check before heading deeper into the Xfinity support forest?

Hello @user_489160! Just to ensure that a download didn't get hung up, can you please disconnect the coaxial cable from your modem and unplug the power cord from its power source for about 1 minute, and then reconnect everything. Once the power cord and coaxial cable have been reconnected, can you please let me know if your issue persists?

Back closer to start...   Download  ~600Mbps (30% less than start) and upload ~5Mbps.  Better but that is less than 1/2 of subscribed download bandwidth.

Thank you for checking for us. @user_489160 Can you tell us more about the devices you have connected. With your modem do you have a separate router, splitter, amplifier or extender connected? 

Do you use a VPN? 

What type of device are you using to run the speed test on?
